It is standalone with lcd display, portable device with battery. This project aim to provide an RF gadget but useful instrument for enthusiast.The default firmware main function is used for antenna performance measurement. If you need more test functions, please update the firmware to "nanoVNA9004ch.dfu" Technical data: - Display: 2.8 inch TFT (320 x240) - Power supply: built-in lithium battery - Measurement range: 50KHz-900MHz (default firmware) - RF output: -13dbm (maximum -9dbm) - Port SWR: < 1.1 - Display: 2.8 inch TFT (320 x240) - Size: 54mm x 85.5mm x 11mm - Weight: 63 grams - Full set of accessories: main unit / 1 set, 3 SMA male calibration parts Set the frequency range (STIMULUS>START/STOP or CENTER/SPAN) Calibration (CAL) Select display format and channel (DISPLAY) Save (SAVE) You can change the display format and channel selection at any time. In the normal test mode, tap the right area of the screen or press the dial switch to call up the menu.Tap the screen or turn the wheel switch to select a menu item. The unit is in the initial state (no data is stored in 0) Scan range 50KHz  ̄ 300MHz (50KHz  ̄ 900MHz if it is 900M firmware) Track 1: LOGMAG CH0 (reflection) (default firmware) Track 2: SMITH CH0 (reflection) (default firmware) Track 3: LOGMAG CH1 (pass) (requires flash nanoVNA9004ch.dfu firmware) Track 4: CH1 stage (pass) (requires flash nanoVNA9004ch.dfu firmware) -Mark 1: Open Not calibrated. We will test before shipment and calibrate the directly connected SMA port. The calibration data is stored in state 0 and the next time it is turned into state 0 data. calibration: Calibration with the specified mechanical calibration requires three loads: open, short and load.The calibration data is saved as user calibration data. It can be saved to status 0 and can be automatically loaded at the next power�on. It can be saved to status 1-4 and can be loaded via the RECALL menu. Click the CALCALIBRATE menu to open the calibration interface, then connect open, shortAnd load three loads, and click on the menu corresponding to calibrate port 0. This unit comes with a simple calibration kit. For the male calibration unit, S is short-circuited (SHORT), L is loaded with (LOAD) 50 ohm load, and internal is open (OPEN). For the female calibration part, the short circuit (SHORT) is used for short-circuiting the solder on the back, the (LOAD) 50 ohm load is applied to the two 100 ohm resistors, and the open circuit (OPEN) is used for the open circuit.Isolation calibration of port 1 requires two load loads to connect port 0 and port 1 for best isolation. Usually the user has only one set of calibration loads for port 0. When there is only one load calibration piece, simply connect the loadcalibration piece. To port 1, port 0 remains open and then press ISOLN tocalibrate. The pass-through calibration for port 1 requires only the RF cableto be used to connect port 0 and port 1 and then press the THRU menu tocalibrate.After the calibration is completed, press the DONE button to pop up thesave interface to select the desired state for saving.After the calibration is completed, you can connect the three calibration pieces to port 0 again.Check whether the calibration is correct through the SMITH diagram. The correct calibration should be: when the connection is open, the curve should be concentrated on the far right side of the SMITH circle. When the connection is short, The curves should all be centered on the leftmost side of the SMITH circle. When connecting LOAD, the curves should be concentrated in the middle of the SMITH circle. Connect port 0 and port 1 using an RF cable and see that the S21 curve error should not exceed 0.5 dB. If the calibration data is found to be abnormal, it should be recalibrated.|If calibration has been applied, the CAL status is displayed on the left side of the main screen. C * is the state in which the unsaved calibration value is applied (this value will disappear after restart). C0 ~ C4 0 to 4 means that the saved calibration value has been applied to one of the save locations. Save is not saved When you save by operation, it changes to this state. C Each character shown below indicates that the following calibration term has been applied: D: Direction, R: Reflection Tracking, S: Source Match, T: Transmission Tracking, X: Isolation, C* Note: nanoVNA3004ch.dfu nanoVNA9004ch.dfu Both firmwares have the above C* functions. The factory default firmware cancels this feature! Select the display channel and display type: Through the menu's DISPLAYTRACE item, you can choose to open or close the corresponding display channel.The color of the channel is the same as the color of the interface curve. The display channel of the last operation is the active tracking channel. The FORMAT, SCALE, CHANNEL operations of the menu are valid for this display channel. The display type can be modified by DISPLAYFORMAT in the menu, DISPLAYSCALE can Adjust the scale of the scale, and DISPLAYCHANNEL can select the measured port. Set the frequency range: There are three main and frequency range related parameters: start frequency, center frequency and stop frequency. The relationship between them is satisfied: Fcenter = (fstart +fstop )/2 Fspan= fstop- fstart Where fspan is the span. The center frequency of the current screen is set by STIMULUSCENTER in the menu, and the values of the center frequency and the span are displayed on the left and right sides of the grid, respectively. Click in the lower right corner of the pop-up setting value screen to pop up the soft keyboard and input the corresponding frequency value through the soft keyboard. Pay attention to the following points during use: Modifying the center frequency will modify the start frequency and the end frequency under the condition that the span is kept constant (except when the start frequency or the end frequency reaches the boundary). When the zero span is used, the start frequency, center frequency, and termination frequency are the same.At this time, port 0 can be used as a signal source of a fixed output amplitude, but it is necessary to pay attention to the use of the clock signal generator S5351 as the most signal source, and the output signal is square. Wave, containing large odd harmonics. Set the frequency range through the menu's STIMULUSSPAN, and display the center frequency and span value respectively on the left and right sides of the grid. Click on the lower right corner of the pop-up setting value screen to pop up the soft keyboard and input the corresponding frequency value through the soft keyboardPay attention to the following points during use:Modifying the span will automatically modify the start and stop frequency of the spectrum analyzer.When the span setting exceeds the maximum value, the spectrum analyzer enters full span mode.When zero span is used, the start frequency, center frequency, and end frequency are the same.Set the starting frequency through the menu STIMULUSSTART, and display thevalues of the starting frequency and the ending frequency on the left and right sides of the grid respectively. Click on the lower right corner of the pop-up setting value screen to pop up the soft keyboard and input the corresponding keyboard through the soft keyboard. Frequency value. Pay attention to the following points during use: Modify the starting frequency to modify the center frequency and span value together before the span reaches the minimum value (parameter modification caused by the span change, see the description of the span), continue to increase after the span reaches the minimum value. Change the termination frequency. When zero span is used, the start frequency, center frequency, and end frequency are the same. The frequency is terminated by the STIMULUSSTOP setting of the menu, and the values of the starting frequency and the ending frequencyare displayed on the left and right sides of the grid respectively. Click on the lower right corner of the pop-up setting value screen to pop up the soft keyboard and input the corresponding keyboard through the soft keyboard. Frequency value. Pay attention to the following points during use: Modifications in the termination frequency cause changes in span and center frequency, which can affect other system parameters.See the introduction in the Sweeping section for details. When zero span is used, the start frequency, center frequency, and end frequency are the same.
